Ches Buss, Port NT OFFICE Y., assignor to Henry ter Application January 28, 1944, Serial N6. 520,054 1 Claims. (of. ass-14s) My invention is directed to an improved fuel atomizing device. 4

One of the objects of my device is to provide a fuel atomizing device whereby not only is good atomization of the fuel obtained, but by employing a plurality of cooperating nozzles or groups of nozzles I obtain the very. much desired control 1 of the shape and direction. of the flameresulting from the combustion of the fuel being handled.

Another object of my'invention is to provide a fuel atomizing device wherein although I em-; ploy-a plurality of cooperating .nozzles a wide range of discharge manipulation. I I Y My invention also provides a device with which heavy oilis easily atomized, inasmuch as there is astraight, through flow for the oil, as'distingiiished from present day practice wherein oil nozzles are equipped with tangential slots which setup rotation in the oil. I

Still another object of the invention isto provide a construction embodying groups of nozzles so that several different types of oil may be time and combined so as to form a single flame, thereby insuring a high degree of combustion. By employing groups of tain various shapes of flame so as to obtain high emciency with combustion chambers. of varying shapes and capacity.

The nibs, that-is, the members through which the oil orother fuel discharges directly, are readline'22 of Fig. 1;

Fig. 3 is an end view of the nozzles or nibs; Fig. 4 is a section taken on the line 4-4 of Fig. 2;

Fig. 5 is apart sectional elevational view of another embodiment of the invention; Fig. 6 is a part sectional elevational view of still another embodiment of the invention;

fig. 7 shows in part sectional elevation afurther embodiment of the invention wherein several pairs of nozzles are-independently controlled;

' Fig. 8 is an end view of Fig. 7; and Fig. 9 is a section on theline 9-9 of Fig. '7. Referring to the drawings in detail and first of nozzles which may or may not be of the same design, I am able to chis obtained by simple valve 14 additionally is all to Figs. 1 to 4, inclusive: 2 designates the fuel supply line, 4 the feed tube and 6 the nozzle body. The .fuel supply line is of course connected to the feed tube, as illustrated, and is controlled by valve 8.

The nozzle body 8 i screwed upon the discharge end of the feed tube 4 and is provided centrally with fuel passageway l0, and at opposite sides of this passageway with fuel passageways l2. The passageways I 2 are diametrically opposite each other and precisely in line with the center of fuel passageway I0.

Mounted in the outer end of the nozzle body 8 are two pairs or groups of nozzles l4 and it.

Each of the nozzles 14 is provided with a longitudinally extending fuel passage or bore "3 extending completely through end of each of these bores communicating at all times withcentral fuel passage |ll.- Each nozzle provided with a cross fuel passage 2ll extending completely through the nozzle, at a or other angle desired to the longitudinal axi of the nozzle body 6. The inner end of each of the fuel passages or bores 20, that is, the end nearest the longitudinal axis-oi the nozzle body, isprovided with tip or nib 22. These tips or nibs are held in place by a threaded cap washer 24. The outer ends of each of the fuel passages l8 and 20 are closed by caps 26 and washers 28. 1

This is a very excellent construction,in that it permits the nozzles to be cleaned with the minimum of effort, and also permits the nibs 22 to be cleaned or changed whenever desired.

The two nomles ii are similar in construction to the nozzles l4, so that it will be unnecessary to describe them in detail. It should-be noted, however, that the fuel passage 18 of one ofv these nozzles is in constant communication with one of the side bores l2, while thefpassage III of the other nozzle isin constant communication with the other of the side bores l2.

The inner end of the central fuel'passage I 0 is provided with a needle valve 30, which extends lengthwise of thefeed tube wheel 32. I

It has already been pointed out that the fuel is supplied to the nozzle groups through valve controlled supply line 2. This line is in direct communication with the feed tube 4, and the nozzles I are in constant communication with this tube by way of bores I8. Consequently any adjustment of the valve 8 in thesupply line 2 varies conditions at the nibs of this nozzle group.

. On the other hand, while the. bore or fuel passage I0 is in communication with the feed tube 4, this the nozzle, the inner I 4 and is controlled by scope of my invention.

as illustrated in Fig.

at the discharge end of the equipment, so as not only to obtain most eflicient combustion but by varying the flame shape the equipment is capable of use at very high efficiency in combustion chambers of different dimensions as well as shapes. I

It will be appreciated from the foregoing that in laying out the nozzle arrangement care is exercised to insure that the fuel streams will impinge upon each other with great accuracy. It will be appreciated also that while I have shown thenozzles set at a 45 angle to the longitudinal axis of the feed tube, this angle may be varied as desired.

It is to be understood too that I have shown two groups of nozzles merely for descriptive purposes. This number may be increased as may be desired without departing from the spirit and I have found, however, with but two' groups of nozzles I not only obtain excellent atomization of the fuel, but, which is of equal and even of major importance so far as my invention of the atomized fuel and hence of the flame as the fuel is burned. It is essential to my invention that the fuel after atomization be controlled in that controlled atomization is the desideratum rather than the mere release of atomized fuel into a combustion chamber.

Referring to the embodiment of the invention 5, the fuel supply line is designated 2 and the feed tube is designated 8,. while the supply of fuel trolled by the valve 8. a

As in Fig. 1, the'nozzle body 8 is screwed upon the feed tube-and carries pairs or groups of nozzles ll and I8. These nozzles are of the same construction as those of Fig. 1, and hence it is unnecessary to describe them in detail.

Inv this embodiment of the invention I have omitted the needle valve 3 8 of Fig. 1, retaining, however, .the all mounted in the same head and so disposed that the fuel streams will impinge upon each other. By regulating the valve 8 the desired control of the atomized fuel is obtained.

.In the embodiment of my invention as trated in Fig. 6 I provide an carrying nozzle body 8. As in the other embodiments of the invention illustrated the nozzle body carries nozzle groups I and I8. It is to be noted. however, that in this embodiment of my invention only the nozzles M are in communication with the feed tube 38. The fuel supply to this tube and hence to the nozzles H is controlled by valve 38.

Extending through the feed tube 38 is another feed tube 48,,the fuel passing therethrough being controlled by valve 42. The inner end of this tube is screwed into an internal projection or boss which is integral with the nozzle body 8, and which communicates only with the nozzle group illus- Y l8. The internal construction of the n zzles II p and may be the same as Fig. 1. r is to be noted, however, that nozzle group I4 is controlled by valve 38, while group I8 is controlled by valve 42, each group independently of the other. This permits two different fuels to be employed at the same time, which is'of considerable advantage in that by utilizing two diflerent types of fuel,

is concerned, I obtain excellent control to the feed tube is confeature of having several nozzles outer feed tube 38,

8 construction to the nozzles of Fig.

illustrate and describe invention I provide in one flame a high degree of comb tion is obtained.

For example, I may burn a very high flashpoint oil, which is ordinarily quite diflicult, by feeding this high fiashpoint fuel through one nozzle group while feeding low flashpoint fuel through the other group.

Referring to Figs. '1, 8 and 9: In this embodiment of my invention I have provided a further refinement of my invention, in that I have provided three groups of nozzles with a separate control for each group.

38 designates an outer feed tube mounting the nozzle body 8 which in this construction carries three groups or pairs of nozzles, '58, 52 and 84, and the feeding of fuel to any group is independent of the feeding of fuel groups.

It will be apparent from Figs. 7 and 9 that the nozzle body 8 is bored as illustrated at 58 so as to provide fuel ducts communicating with feed tube 38 and nozzle group 80. The fuel feed to feed tube 38 is controlled by valve 38.

Extending along the interior of the feed tube 38 is a second feed tube 58. This tube is out of communication with the feed tube 38, and is controlled by valve 88. The communicates with a central bore 8i in the nozzle body 8, this bore in turn communicating with fuel bores 82 leading to the nozzles 82.

Intermediate the feed tubes 38 and 58 is a third feed tube 84, controlled by valve 68. tube is out of communication with feed tubes 38 and 58, but at its inner end constantly communicates with ducts 88 leading to nozzles 84.

The nozzles 50, 52 and '54. may be similar in 1, so that it becomes unnecessary to them in any detail.

It will be seen tha in this embodiment of my three groups of nozzles each independently controllable so that excellent control of combustion is obtained, even more refined than the construction of Fig. 6.

It will be appreciated pingement of the fuel streams upon each other.

I wish it to be understood that changes may be effected in the details of construction and arrangement of parts hereinabove described without departing from the spirit and scope of my invention.
